Marxist-Leninists in an overwhelming majority oppose the current Russian government.
No, they don’t.
Of course there are stupid idiots everywhere, including ml, and there are bound to be “leftists” whose entire ideology is “USA bad, so NATO bad, so Putin good”
If that wasn’t their whole ideology, they wouldn’t be tankies. Even in ml, which is much less radical than grad or hexbear, discussions are firmly split between “Russians go the fuck home” and “nato provoked Russia” and the usual idiot talking points. Just search “Ukraine” on ml and see what people say in the comments and what he’s upvoted.
